  • Patent number: 8152679
    Abstract: The invention relates to rotary units and rotary mechanisms that are suitable for use in numerous applications. Rotary units typically include rotational components that are configured to rotate. In some embodiments, for example, multiple rotary units are assembled in rotary mechanisms such that neighboring pairs of rotational components counter-rotate or contra-rotate relative to one another during operation of the rotary mechanisms. Rotational components generally include one or more implements that are structured to perform or effect one or more types of work as the rotational components rotate relative to one another in a given rotary mechanism. In certain embodiments, implements are configured to rotate and/or to effect the movement of other components as rotational components rotate.

  • Patent number: 6799120
    Abstract: The present invention includes methods for generating combinatorial libraries on solid phase supports in which increased productivity is achieved by pooling all common steps in synthesis without using a tracking or coding system to record the synthetic history of each compound. Methods for generating combinatorial libraries in which containers with random mixtures of solid phase particles are divided and combined together in non-random ways without the exchange of particles between containers are also provided. Various products are optionally produced in multi-stage syntheses according to the invention, such as oligomers and synthetic non-repetitive organic molecules. The methods additionally relate to the identification of each library component without adding extra synthetic, physical, optical, or electronic encoding steps during library synthesis. Combinatorial synthetic systems are also provided.

  • Patent number: 6723555
    Abstract: A fermentation apparatus is constructed to produce a known and repeatable amount of untainted fermentation product using multiple fermentation vessels. To facilitate further processing compatible with other product processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame. The container frame is configured to hold the sample vessels during fermentation and to transport the vessel array to or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula array is configured such that each cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because the fermentation volume for each individual sample vessel is smaller than a bulk fermentation apparatus, the fermentation product yields are predictable and cell growth rates can be effectively optimized.

  • Patent number: 6682703
    Abstract: The present invention relates to parallel reaction devices that include reaction blocks having arrays of reaction wells. Devices of the invention also typically include lids having arrays of protrusions disposed thereon, which protrusions axially align with the reaction wells, and/or attachment components that include hinges that permit lids to be removed from reaction blocks.

  • Patent number: 6659142
    Abstract: A system and method for preparing and dispensing fluid mixtures is provided. Fluid wells are positioned below a plurality of fluid dispensing devices, such as syringes configured to dispense fluid into the individual fluid wells. The fluid dispensing devices are configured to be positionable relative the fluid wells to enable different fluid dispensers to be sequentially positionable over a particular fluid well. A controller controls the relative movement between fluid wells and the fluid dispensing devices. In a preferred embodiment, the controller selectively moves multi-well vessels in one direction and moves the fluid dispensing devices in a second direction so that when directed by the controller, a selected fluid dispensing device is enabled to deposit a determined quantity of a fluid into a selected individual well of the multi-well vessels.

  • Patent number: 6625546
    Abstract: Methods of identifying predicted or actual structures of members of a chemical or physical library are provided. The methods provide for the direct identification of compound structure following combinatorial synthesis using molecular mass measurements of individual compounds, thereby eliminating the necessity of encoding synthetic steps. The analysis of mass spectrometric data for sets of related compounds reveals compounds that are missing in a group of related compounds and identifies compounds that do not belong to a group of related compounds due to unexpected chemical, physical, or biological transformations. The methods may be applied to any group of compounds originating from chemical reactions where one reactant is common to the synthetic transformation. One particular application of these methods is in the analysis of the products of combinatorial synthesis. Systems, computer programs products, and kits are additionally provided.
